Code C2783 Description

The longitudinal accelerometer is contained in the sensor cluster. The sensor cluster measures the vehicle acceleration and deceleration and then sends the signal over the controller area network (CAN) communication lines to the Anti-Lock Brake System (ABS) module. Voltage is supplied by the circuit. The ground is provided through the circuit. The CAN communication is transmitted through the circuit.
